Why Plant Marigolds by Tomatoes

Marigolds and tomatoes are two plants that make great companions in the garden. They provide numerous benefits to one another, making it a wise choice to plant them together. Here are some reasons why:

Benefit #1: Pest Control

Marigolds can help control pests that commonly plague tomato plants, such as aphids, nematodes, and whiteflies. Their strong fragrance and roots work together to keep these pests away, making marigolds a natural pest control option for tomatoes.

Benefit #2: Attracting Beneficial Insects

Not all insects are harmful to tomato plants. Some, like ladybugs and bees, are actually beneficial. Marigolds attract these beneficial insects, which can pollinate the tomato plants, improving their health and yield. Ladybugs can also help control aphids, which can damage tomato plants.

Benefit #3: Soil Enrichment

Marigolds are also known for their ability to enrich the soil. They produce a chemical that helps repel harmful root-knot nematodes, and their roots help improve soil structure and moisture retention. Tomatoes benefit from this enriched soil and grow stronger and healthier.

How to Plant Marigolds with Tomatoes

Planting marigolds with tomatoes is easy. Simply sow marigold seeds around the outside of your tomato plant, or in between tomato plants in your garden bed. The marigolds should be planted about six to eight inches away from the tomato plants to give them enough space to grow.

It is also important to note that not all marigolds are created equal. French marigolds, Tagetes patula, are the most commonly used marigold for companion planting with tomatoes. They have a strong fragrance that repels pests and their roots help improve soil structure. However, African marigolds, Tagetes erecta, do not have the same pest-repelling properties as French marigolds and are not recommended for companion planting with tomatoes.

Conclusion

Planting marigolds with tomatoes is a simple and effective way to improve the health and yield of your tomato plants. With their natural pest control abilities, ability to attract beneficial insects, and soil enrichment properties, marigolds and tomatoes make a great pairing. Try it in your garden this season and see the benefits for yourself!
